Atomizer.



UNITED STATES PATENT OFF cE.

ALLEN DE VILBISS, OF TOLEDO, OHIO.

ATOMIZER.

SPEOIFIGATION forming part of Letters Patent No. 704,780, dated July 15, 1902.

l Application filed November 4, 1901. $erial No. 80,938. (No model) To all wi l/01m it may concern:

Be it known that LALLEN DE VILBIss,a citi zen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Atomizers; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the figu res of reference marked thereon, which form a part of this specification.

My invention relates to that class of atomizers or spray-forming devices in which the liquid to be sprayed is drawn from its vessel through a suitable conduit by a stream-of air,

kets, Will not leak, andwhich maybereadily and easily taken apart for inspection andfor cleansing. I attain these objects by means of the devices and arrangement of parts hereinafter described and shown, and illustrated in the accompanying drawings, in which Figure l is a perspective view of my device with the cap hereinafter referred to detached; Fig. 2, a central longitudinal sectional elevation of my device with the cap in place, and Fig.3 a side elevation of the same. The drawings for the sake of clearness show my device on an exaggerated scale.

Like numerals of reference indicate like parts throughout the drawings.

In the drawings, 1 and 2 aretubes which at some distance from their extremities are bound together in nearly parallel relation by metal band 3. The tube 1 is connected with an air-compressor bulb, and the tube 2 is connected with the chamber of the vessel which contains the liquid to be atomized. The bulb and the vessel here referred to are omitted from the drawings, as they form no part of my turned inwardly, so that their ends point toward each other. The tubes are here reduced in diameter externally, as at 4, as illustrated in Fig. 2, for the purpose hereinafter described.

5 is a block or head formed in general outline,preferably, as a cube. Two opposite sides of this block have circular recesses 6 and 7. These recesses are exactly opposite each other, having coincident axes, and are of such diameter as to receive with a snug fit the reduced ends of the tubes 1 and 2. These tubes at their outerextremities may be sprung apart and the block may he slipped in between the separated'tuhe ends. The tubes by reason of theinresiliency pinch and hold the block in place, and the ends of the tubes form a swivel upon which the block 5 may be rotated.

The shoulders of the reduced end portions of the tubes resting against the sides of theblock form tight joints, which prevent leakage.

One of the unrecessed sides pf the block 5 has a projection 8,which is cylindrical in form and is exteriorly screw-threaded. Projecting centrally from the outerflat side of the part 8 "is a nozzle-point 9.

p This point has a central bore 10,whichextends into the chamber 6. A bore 11 extends from the flat face of the parts 8 into the chamber 7.

12 is an interiorly-screw-threaded cap, having a central orifice 13 and a hollow or chamber 14. This cap screws onto the part 8 such distance that the point 9 projects into and part way through the orifice 13, thus forming a thin annular opening surrounding the extremity of the point and connecting the chamber 14: and the orifice 13. The bore or passage 11 connects, the chambers '7 and 14.

The operation of my device is:. as follows: Assuming that the parts are assembled as shown and that the tube 1 is connected with an air-compressor and that the tube 2 is conand discharged as a spray or vapor.

flow of the air around the point 9 will create a partial vacuum, causing the liquid to flow through the tube 2, chamber 6, orifice 10, and into the opening 13. Here the liquid mingles with the stream of air and is finely subdivided It will be seen that the stream of mixed air and liquid may be discharged in any direction in the plane of rotation of the head or block 5 by turning this part upon its bearings to the desired position.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In an atomizer, a head having two of its opposite sides formed with chambers therein, a pair of arms which enter and engage said chambers,a chambered cap adapted to engage said head and having a central orifice therethrough, a nozzle-point projecting into said orifice and connected with one of the chambers of said head, and connections between the other chamber of the head and the chamber of the cap.

2. In an atomizer, a head having two chambers therein, one of which has an air-supply connection, the other of which has a liquid supply connection, a chambered cap detachably secured upon said head and havinga central aperture, a spraying-point upon said head which enters said aperture and which has an axial passage connected with one of the chambers in said head, and connections between the chamber of the cap and the other chamber of the head.

In testimony whereof I affix my signature in presence of two witnesses.

ALLEN DE VILBISS.
